Colin Campbell Mitchell was a British Army soldier and politician. He became a public figure in 1967 as the commanding officer of the 1st Battalion of the Argyll and Sutherland Highlanders. Forces under his command reoccupied the Crater district of Aden which had been taken over by local police mutineers in what became known as "the last battle of the British empire". The reoccupation and subsequent control of the Crater were controversial and Mitchell resigned his army commission in 1968. Subsequently, he became a Conservative Member of Parliament and served one term from 1970 to February 1974. After participation in a failed business venture he subsequently worked as a security and military consultant. In 1989 Mitchell took a leading role in the Halo Trust, a not-for-profit organisation undertaking mine clearance in former war zones.

The Argyll and Sutherland Highlanders (Princess Louise's) is a light infantry company (designated as Balaklava Company, 5th Battalion, Royal Regiment of Scotland) and was a line infantry regiment of the British Army that existed from 1881 until amalgamation into the Royal Regiment of Scotland on 28 March 2006.
